CLARENCE A. BISHOP, OF NEW YORK, N. Y.

CALCULATING-MACHINE.

Application filed February 8, 1912.

To all whom it may concern:

Be it known that I, CLARENCE A. BISHOP, a citizen of the United States, residing in the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a certain new and useful Calculating-Machine, of which the following is a specification.

This invention is a calculating machine, particularly adapted for calculating wages, although it will be apparent from the hereinafter detailed description that the principle of the machine may be adopted for other purposes,

One of the principal objects of the invention is to calculate wages at a given rate for any period of time, such as a day or any fraction thereof, expeditiously, automatically and accurately.

YVith this object in view, the invention embodies a suitable type surface and a cooperating platen, the operative position of which platen relative to the printing surface is determined by a suitable designating expedient on a time card.

In the practical embodiment of the invention herein illustrated and described, the type surface is in the form of a rotatable printing cylinder provided with a plurality of series of printing characters, each series representing the wages at a given rate for various periods of time. In the said embodiment, the platen is shown as a pivoted hammer mounted on a carriage, whereby it may be moved into different operative positions, determined by the time card as specified.

It is preferred to have the designating mark on the time card in the form of a recess or perforation which, when the card is positioned in the machine, cooperates with a member on the carriage to determine the position of the printing hammer with respect to the wage scale by printing the particular wage value on the card. It is preferred to have the said member cooperate with the printing hammer in such manner that when it reaches its registering position with reference to the recess or perforation on the card, the printing hammer is released from its normal position so as to automatically effect the printing operation.

Other features of the invention, in addition to those to which reference has been made, will be apparent from the hereinafter detailed description.

Specification of Letters Patent.

Patented Dec. 9, 1913.

Serial No. 676,229.

In the accompanying drawings, I have illustrated one practical embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 is a plan view of the new calculating machine, the dotted lines illustrating the position of a time card when said card is first placed in the machine and prior to the calculating operation. Fig. 2 is a vertical section taken longitudinally through the machine on the line 2-2 of Fig. 1, parts being shown in elevation. Fig. 3 is a vertical cross section on the line 33 of Fig. 2 looking in the direction of the arrow. Fig. 4: is a detail view of a part of the machine illustrating the primary guide by which the position of the time card is determined when said card is placed in the machine. Fig. 5 is a plan view of a part of a rotatable printing cylinder illustrating a plurality of wage scales thereon. Fig. 6 is a detail view of a trip and a yieldable toepiece for cooperation with a notch in a time card. Figs. 7 and 8 are views of time cards adapted to be used in connection with the machine.

In the practical embodiment of the invention shown in the drawings, a supporting frame A is provided with a table B, a chamber a and posts a for supporting a guideway 0 for a movable carriage C.

Table B may be of any suitable or preferred construction, and it is positioned upon the frame in a manner to close the top of chamber a, said table B being secured in any suitable way to the frame. The table is provided with a longitudinal slot 6, the width of which is suflicientto expose a number of type bars, having wage scales, on a rotatable carrier as will presently appear, but in order to expose only one of the wage scales, the table is provided with a plate B having a slot 6 the width of which is sufficient to expose one of the wage scales.

The posts a extend upwardly from table B, said posts being positioned near one side edge of the table and at the respective ends thereof. the post near the left hand side of the table in Fig. 1 being somewhat wider than the post at the opposite end of the table. The guideway for movable carriage C is shown as consisting of parallel rods which are fixedly supported by posts a, one of said rods being positioned below the BEST AVAILABLE COP.

other, and the two rods forming a guideway at one side of the slots in table B and plate B, respectively, said guideway being parallel to the slots. \Vhile I have shown and described the guideway as consisting of parallel rods 0, c, it is evident that other forms of guideways for the carriage may be employed.

Carriage C is shown as a plate provided with apertures which receive rods 0, a form'- ing the guideway, whereby the carriage is mounted or supported on the guideway for sliding movement freely thereon, said guideway operating to limit the carriage to movement in a rectilinear path and in a direction parallel to the slots in the table and top plate thereon. Said carriage is provided with a transverse slot d within which is pivotally supported a platen E adapted for cooperation with a printing cylinder F to be presently described. The carriage is adapted to be moved along the guideway by any suitable means, a knob or finger piece D being provided on the carriage for this purpose. As shown, the knob is attached to the top of the carriage, and extends upwardly therefrom, so as to be positioned for convenient access by the operator.-

Platen E is shown in the form of a hammer or lever, said hammer or lever being bent to the form shown more particularly in Fig. 3 so as to pass through slot d in the carriage, one arm of the lever being pivotally supported in the carriage ona pin 6. The operative end 6' of the hammer overhangs the slot in top plate B, and normally this hammer is retained in a position free from contact with the slotted plate by a suitable latch mechanism to be presently described. The hammer is actuated forcibly in one direction when released from the latch by a spring g, one end of which is connected to the pivoted arm of the hammer, whereas the other end of the spring is anchored on a pin 9 extending outwardly from carriage C. If desired, a spring G may be mounted on the carriage so as to act against the hammer in a direction to press it upwardly from the slotted plate B, and thus retain the hammer in a position free from contact with an inked ribbon, but as the hammer is locked in a raised position by the action of the latch, spring G may be omitted. For lifting the hammer, it is preferred to employ a pressure piece 6 the same extending upwardly from the hammer and positioned near to knob D, in order that the operator may grasp said knob D and pressure piece 6 between the fingers of the hand, whereby the hammer may be lifted from contact with an inked ribbon and the carriage moved along the guideway by the operation of one hand.

The frame A is shown Fig. 2 as having its end members provided with bearings f for a horizontal shaft f which carries the printing cylinder F. Said printing cylinder is positioned within chamber a of the frame and below table B, whereby the printing cylinder is substantially housed or incased within the chambered frame or base of the machine. The shaft f of the printing cylinder extends at one end beyond the frame, and it is shown as having an operating member F secured thereto, said operating member being preferably in the form of a hand wheel which is provided with a scale, as shown in Figs. 1 and 2, the numbers on which scale represent the rates of the wage columns, the positions of said numbers corresponding to the wage columns carried by the printing cylinder. The hand wheel is outside of the casing for convenient access by the operator in order that the printing cylinder may be rotated whenever it is desired to bring one of the wage columns into position below the slot 72 in plate B.

The printing cylinder is constructed to receive a series of type bars, each type bar being provided with printing characters in the form of a column of figures representing the value of the wages for adays labor, the units of the column of figures being based upon calculations of fractions of an hour multiplied by the wage rate per hour. In the illustrated example of each wage column. itis assumed that ten minutes is the unit of time, and this unit of time is multiplied by the rate per hour. The column of figures of each wage scale increases in value from one end of the column to the other, the highest figure in the column representing a full days value in wages, and the lowest figure in the column being the value in wages for ten minutes of time. The figures in one wage column are based upon a certain rate per hour, the figures in the next rate column are based upon a different rate per hour, and so on throughout the series of wage columns which are carried on the cylinder F. The wage columns are positioned on the cylinder correspondingly to the numerals on the hand wheel F; thus the wage column based on a rate of twenty-four cents per hour will be positioned on the cylinder in register or alinement with the numeral 24 on the hand wheel, and so on throughout the series of wage columns and figures on the cylinder and the hand wheel, respectively. As shown, cylinder F is provided with a series of longitudinal channels h, and in these channels are positioned type bars H, the latter being retained in fixed positions within the channel by any suitable means (not shown). Obviously, the type bars are provided with numerals representing the figures in the wage scales, and these type characters are cast on the type bars, or pro duced thereon by the elcctrotypin process. The type bars run lengthwise of the cylin- BEST AVAIL-ABLE COP.

der, and they are parallel to each other, said type bars being spaced on the cylinder so that the printing characters on one type bar when the cylinder is adjusted to aline or register the type bar with the slot 6 will be exposed through the said slot to access by the operative end 6 of hammer E. The cylinder is adapted to be rotated by the manipulation of hand wheel F for the purpose of bringing either of the series of type bars into register with the slot 6 The cylinder is retained in its adjusted position by any suitable form of detent, as for example, the spring detent H shown in Fig. 3. Said detent is a spring attached at one end to the bottom of easing A, said spring having an ofiset it adapted to enter the space between any two of the type bars H, whereby the offset of the spring engages the type bars with sufficient frictional contact to preclude accidental rotation of cylinder F.

Suitable means are provided for inking the type bars, whereby printed impressions may be obtained upon a time card when hammer E is actuated. In the embodiment of the invention shown in the drawings, the inkin mechanism consists of a ribbon I extending below the slotted plate B and across the column of figures constituting the printing characters on one type bar. The respective end portions of ribbon I are coiled on spools i, i positioned within compartments 2' of easing A, and at the respective ends of cylinder F. Each spool is carried by a shaft 1 supported in suitable bearings on frame A or compartment said shaft 1 being extended beyond the front of the frame and provided with a knurled knob 2' whereby the spool may be rotated for the purpose of winding the inked ribbon upon one spool and unwinding the ribbon from the other spool. It is evident that any kind of inked ribbon may be used, and that said ribbon may be adjusted from time to time in order to present a freshly inked surface over the printing characters of the wage columns on the type bars. As shown, the inked ribbon is positioned between the type bars of the printing cylinder and the path of travel of the hammer E as it is moved back and forth with carriage O relative to the table B. A time card upon which the imprint is to be made is intended to be placed upon table B and top plate B, said top plate being positioned intermediate the time card and the inked ribbon, thereby preventing the direct contact of the time card with the inked ribbon so that ink from the surface of said ribbon will not be trans ferred to the time card in the operation of placing said card into position in the machine or removing said card from the machine.

J designates a guide bar for limiting the insertion of the time card when placing the same into the machine preliminary to the operation of printing the wage value upon said card. This guide bar J is attached to table B at one side of the slots 7) in the table, and b in plate B. The guide bar extends a suitable distance above the. table and the plate, and it is adjacent to the slot 72 in said plate B, whereby the time card, when inserted into the machine, will come into contact with the guide bar, and the latter will determine the extent of the edgewis'e insertion of the card into the machine.

In addition to guide bar J, the machine is provided with a guide J which extends forwardly from the guide bar and is very close to, or extends part way across, slot 6 in plate B. This guide J coiiperates with a corner of the time card upon which the imprint is to be made. As shown in Fig. 4, the guide J is adapted to fit into a notch provided in a corner of the time card. Said guide determines the relation of the card to a wage scale on the type bar of the printi'ng cylinder, whereby a time scale or scales on each time card will be brought into correct relation to the column of figures composing one wage scale of theprinting cylinder.

For the purpose of determining the position of the printing platen or hammer relative to the desired number in the column of figures of a particular wage scale upon the movement of carriage C along the guideway and the table, I employ a trip? or stop dea vice which is movable with the carriage and is so positioned that it will automatically engage with a predetermined designation which is placed upon the time card by the workman. In the embodiment shown of the trip device, it serves the functions of a latch for retaining the printing hammer in a raised position, as well as for arresting the movement of the carriage and the hammer when the trip device comes into contact with the designation placed upon the time card by the workman prior to the insertion of said time card into the machine. Extending outwardly from carriage C is an arbor or spindle K, the latter being at one side of and parallel to hammer E, whereby the hammer and the spindle are mounted on the carriage for movement therewith. This spindle carries a trip L, the same being shown as a plate or bar mounted loosely upon spindle K for movement freely thereon, whereby the trip is adapted to rock or turn on the spindle. The lower part of thetrip is provided with a recess or chamber Z in which is slidably fitted a toe-piece m, the latter being free to rise and fall within said chamber Z. The toe-piece is pressed normally in a downward direction by a spring '21 housed within the chamber Z, and such downward movement of the toe-piece is limited or arrested by a BEST AVAILABLE COP;

stop pin n, as shown more particularly in Fig. 6, and in dotted lines in Fig. 2. The toe-piece is provided on one side with a bevel, as shown in Fig. 6, so that it will ride over the permanent guide J when the carriage and the devices-thereon are removed toward the left in Fig. 2. The other side of the toe-piece from the bevel is perpendicular to plate B, and thisperpendlcular side of the toe-piece is adapted to come into contact with an edge of the recess or perforation which constitutes the permanent designation which is placed upon the time card by the workman. The trip is actuated in one direction by a coiled spring M fitted loosely around spindle K and having two arms, one of which engages with the pivoted trip and the other with a pin p which is secured to member P, the latter be ing fixed in a suitable way on spindle K. The fixed pin is connected by member I? and spindle K with the carriage, and this pin serves as an abutment for one end of spring M. The upper part of trip 'L carries a latch O, the same being shown in the form of a pin which is attached to the pivoted trip near its upper end, said latch being adapted for engagement with an aperture e provided in hammer E. The spring acts on the trip to press the latch pin into engagement with the aperture in the hammer for the purpose of locking said hammer in a raised position, whereby the operative end 6 of the hammer is normally in a raised position withreference to the slotted plateB'. U

After printing the number representing the wage value for a particplar time'at a specified rate upon the time card, thecarriage O, the hammerandthe parts coopcrating therewith are returned to a normal position over the permanent guide J. When the carriage and hammer are to be shifted lengthwise of the machine, the operator grasps knob D and pressure piece a? for lifting the hammer and sliding the carriage along the guideway. I may, and preferably do, employ means forautomatically lifting and resetting the hammer as the carriage reaches the limit of its movement in the direction toward normal position over the guide J. The resetting device is shown in the form of a stem Q, having a beveled conical end 9 adapted to enter an aperture 1' which is provided in hammer E. The resetting stem Q. is attached rigidly to a post a at the left of the machine frame by suitable means such as the clamping screw 1",

said resetting stem occupying a fixed position on the machine frame and in the path of the aperture 1' in the hammer E. When the carriage, the hammer and the cooperating parts are moved by hand overthe permanent guide J, the beveled end g of resetting stem Q, enters the aperture 0", the stem being so related to the hammer that the beveled end of said stem will ride against one edge of the aperture in a manner to lift the hammer against the tension of a spring g. When the hammer is lifted sufliciently for the aperture 0 in said hammer to come opposite to the latch pin 0, the spring M acts on the trip L to press the latter toward the hammer and thereby move latch pin 0 into aperture e for the purpose of locking the hammer in a raised position. It will be understood that the operation of resetting the hammer and locking it in its raised reset position is performed automatically by stem Q, trip L, and latch 0 upon the return of the carriage and the hammer to a position over the permanent guide, thus relieving the operator from the labor and attention of manually resetting the hammer to an operative position. The machine frame is supported on a table by rubberfeet s of any suitable construction. To one end portion of the machine frame is secured a plate S, positioned to extend over the numerals on the edge of hand wheel F, said plate S having an observation slot 8 through which may be viewed the number on the hand wheel corresponding to the rate of the particular wage column on the type bar which is in register with the slot 5 on plate B.

Various forms of time cards for use by the workmen maybe employed, two forms of such cards being shown in Figs. 7 and 8. The card T shownin Fig. 7 is shown as being provided in one of its corners with a permanent index t, which is preferably in the form of a notch: or recess cut into the cornerof the card; In addition to the permanent index, the card T is provided with words or spaces indicating the department number, the operation, the number or name of the workman, and various other data for identifying the particular job of work performed by the worlnnan. In addition to the foregoing, the card is provided with a col-- umn t at the head of which appears the rate of wages paid to the workman per hour, and said ticket is provided, also, with a scale t referred to as an elapsed time scale. This 115 scale contains numbers from one to eight or more, inclusive, corresponding to the working hours of the day, and each hour is subdivided into intervals of ten minutes. When a ticket or card, such as T, is given to the 12 workman at the beginning of a days work, the proper data is filled in the several spaces, the particular workman being given BEST AVAILABLE COP which, upon the proper insertion of the time scale i More properly speaking, thecard T of Fig. 7 is a job ticket, on which the wage value for one piece of work is to be printed. Accordingly, a job ticket is to be given to the workman with each job of work, said ticket is to be punched at the beginning and completion of the work, and is to be turned in to the accounting department upon the completion of the job.

The time card U, shown in Fig. 8 of the drawings is shown as being provided with a permanent index u, the column a, and spaces adapted to receive various data, the permanent index at and the rate column at being similar to the permanent index t and rate column t of the ticket shown in Fig. 7. Instead of the elapsed time scale t the ticket U of Fig. 8 is provided with a time scale a indicating in hours and divisions thereof the time of startin and completing the work on a particular Job or jobs. Accordingly, the ticket U is adapted to be used for a series of jobs, and said ticket is to be retained by the workman until he completes the days work, at which time the ticket is to be delivered to the foreman. Obviously, the card T may beprovided on one side with an elapsed time scale t and on the opposite side with the starting time scale at",

thus combining the desirable features of thetime cards T, U, shown in Figs. 7 and8, respectively.

The operation is as follows :lVhen a: job of work'is assigned to a workman, he is at the same time given a time card with a rate printed thereon corresponding to the:

wages paid to him per hour, said time card being of one form or another, such as shown in Fig. '7 or 8. Assuming that the card is delivered to the workman at the beginning of the day, it is not necessary for said workman to punch the card, for the reason that the permanent index t or M denotes the beginning of the time of work on the job.

lVhen the workman completes his task onthe job assigned to him, he places the designating character on the card opposite to the division of time on the time scale on the card to denote thereon the time of completing the work. In Figs. 7 and 8, this designating character is a notch t punched in the edge of the card, said notch being opposite to the mark in the time scale denoting the time of completing the work.

slot b Should the workman be furnished with a Fjob ticket of Fig. 7, it is delivered to the foreman when the job is completed. But, should the workman be supplied with a card having the startin time scale of Fig. 8, then the ticket is punched when the first job is completed, and the workman retains the ticket when he starts the second job. The workman then proceeds with his work on the second job, and when the second job is completed, another designating character, such as the notch t is produced in the edge of the card opposite to the mark in the starting time scale denoting the time at which the second. job was completed, and these operations are repeated as often as necessary. At the end of a days labor, or at any other time, the time cards of the workmen are sent to the accounting division of the factory, office, or other business establishment, and these cards are utilized in calculating the wages of the workmen, and in estimating the costs on the particular jobs, the calculating machine of' Figs. 1 to 6, inclusive, being employed in connection with the time cards to expeditiously and economically effect the calculations. The accountant assorts the cards according to the rate scales thereon; thus, all cards filled in and punched by the workmen paid at the rate of twenty-four cents per hour are assorted into one pile, the cards representing the other rates of wages paid to the workmen being similarly assorted' into piles. With the time cards thus assorted before him,-the accountant proceeds to calculate the wages in the following manner :Assuming'that carriage G and hammer E are adjusted to the left of the machine, in the position of Figs. 1 and 2, and-with the hammerl ocked in a raised position over permanent guide J, a time card is selected from a pile, and the cylinder F is turned until the numeralon index wheel F, corresponding to the rate of the selected time card, is below the slot 8, at which time the proper type bar containing the appropriate wage scale is brought into position below slot 6 in the top plate of the table. The time card is now inserted edgewise into the machine until the notched edge of said time card comes into contact with guide rail J the corner of the card; or the permanent index t or u of said card, fitting snugly to permanent guide J whereby the rail J and permanent guide 'J accurately determine the position of the inserted time card with reference to the column of figures on the selected type bar. It is to be observed that the divisions in the time scale on the time card will correspond to the order of the numerals in the column of figures on the particular'type bar which lies just below th The operator now moves the carriage C by pressing upon finger-piece D so its as to'advance said carriage and the hammer along slot 6 and the table, the spring-actuated toe-piece m being pressed into frictional contact with the top face of the card.

Assuming that a job ticket T has been inserted into the machine, the movement of the carriage is continued until the toe-piece drops or falls into notch t of the time card, whereupon the following operations take place: The continued movement of the carriage is arrested by the perpendicular face of the toe-piece abutting against the edgeof the notch or perforation in the card; the toe-piece thus meets resistance and operates to turn tr-ip L on the pivot afforded by spindle K, thus turning the trip against the tension of spring M; the movement of the trip? pulls the latch pin 0 free from engagement with hammer E, thus releasing said hammer, whereupon the spring 9 becomes effective in imparting a sudden downward im-, pulse or movement to the hammer, whereby,

the operative end e of the hammer is forced against the card and against the particular figure in the column of figures constituting automatically into operation by the movement of the trip which disengages the latch from the hammer. The position of the ham-@ mer relative to the wage scale being deter-- mined automatically by the engagement of the trip with the notch of the card, results in the: printed impression being placed upon the card at the point opposite to the notchpro5 duced in the card by the workman, and thusv the value of the wages is computed auto-; matically and mechanically and a record of said wages is made upon the card. After the value of the wages shall have been printed upon the job ticket T, it is removed from the machine, and another ticket inserted in the manner described, whereuponthe operations are repeated.

When a time card U is inserted intothe machine, its position is determined by guides J and J, and the machine is operated to determine the wage cost on the several jobs represented by the card, as follows :After the card is first positioned with notch u in.

operative relation to guide J, the carriage, is moved over the card until toe-piece m contacts with an edge of notch i whereupon the hammer is released and coiiperates with the wage scale on the typebar and with the ribbon to print the wage value for, the first job upon the card, after which the BEST AVAILABLE COP carriage is returned to position over the guide J. The card is now removed from guide J and shifted lengthwise of rail J so that notch t in the card will receive guide J, and then the carriage is again moved along the card until the toe-piece mengages with an edge of notch t thereby arresting the carriage and releasing the hammer for the purpose of printing in column u the wage value for the second job. These operations of printing the wages for the individual jobs are repeated as often as there are notches in the card, and thus the card U has as many calculations printed thereon as there are notches in the edge thereof, the distance between two notches representing the time devoted to each job. The wage values for the work performed by the workman on one or more jobs, as indicated by the notches in the proper card, having been computed, and the desired records obtained, the card is removed from the machine, and another card is placed therein in the manner heretofore described, whereupon the operations of determining the wage values of the workman for the second card are carried out as described. The cards in one pile, representing one rate having been used in the machine to determine the value of the wages to be paid to the different workmen, the operator next proceeds to compute the value of the wages at a different rate as represented by the cards in another pile, preliminary to which the cylinder F is adjusted by manipulating wheel F until the proper rate number thereon appears below slots 8.

It should be remarked that between the operations of computing the wage Values of two successive cards, the operator returns carriage C to its normal position, at which time stem 0 engages with hammer E so as to reset the same for the latch O to again lock the hammer in the raised position, the beveled face of the spring-actuated toe-piece m riding upon guide J so as to bring said beveled toe-piece into a position to rest upon the guide in the normal position of the hammer.

From the foregoing description it is apparent that the operations of calculating wages at any rate and for any predetermined length of time may be accurately and automatically performed, thus relieving the accountant of the labor of estimating or calculating the wages of the workmen on particular jobs.

The invention in its broad aspect is not strictly confined to the particular machine disclosed, for the reason that various modifications in the mechanism may be resorted to without departing from the spirit of the invention. For example, it is not necessary to automatically operate hammer E for the reason that said hammer may be manually operated by thumb-piece 6 when its position relative to the wage column is determined. Again, the invention involves a method or mode of procedure of obtaining a record of the wage value, said method embodying the steps of punching or otherwise marking the card at the completion of the work on a job by the workman, positioning said card in a certain predetermined relation to a wage scale, the figures in which are based upon calculations of certain intervals of time at a specified rate, shifting one element of a printing mechanism into a relation to the wage scale which is determined by the designating character placed upon the time card by the workman, and operating said printing mechanism to secure the desired calculation upon one surface of the card.

Having thus fully described the inven-.
